Abstract
Large single crystals of pure and doped Triglycine sulphate are obtained in the temperature range 44 to 28°C using the falling temperature technique. The divalent ions Ni2+, C02+ and Cu2+ as well as the trivalent Cr3+ and Fe3+ are used as the dopant ions. The effect of these ions upon the speed of growth, crystal parameters, density, crystal morphology, surface relief, color and crystal purity is presented. The variation in the measured physical properties is strongly dependent on the complexes formed by the dopants.
